Dynamic ring classifier for a coal pulverizer



FIG. 1 is a perspective view of a classifier assembly according to an embodiment of the present invention.

FIG. 2 is a rear view of the classifier assembly of FIG. 1, illustrating the adjustable flange, radially outward extending elongate arms, rotator and stator.

FIG. 3 is a section of the stator and rotator portions of the classifier assembly of FIG. 1 within an enlarged partial detailed view, illustrating the labyrinth seal formed by the stator and rotator; and,

FIG. 4 is a section of the stator and rotator portions of the classifier assembly of FIG. 1 within an enlarged partial detailed view, illustrating the stator and rotator in cross section forming a labyrinthian seal.

The broken lines showing are for illustrative purposes only, to show the environment of the dynamic ring classifier in a coal pulverizer, and form no part of the claimed design. 

The ornamental design for a dynamic ring classifier for a coal pulverizer, as shown and described in the attached specification.
